We present a cost-effective service composition algorithm MC4MR aiming at mass customized QoS requirements. If a group of customers raise personalized QoS constraints on a given service, the algorithm looks for a finite number of composition solutions to meet these requirements and realize maximum benefit. To pursue higher cost-effectiveness, we combine multiple individualized requirements together...
In service oriented computing applications, different resources in grid systems are encapsulated abstractly as services. Sometime, single service software can provide valuable service functions for service consumers, but most of the time, single atomic service can not satisfy them. In this case, the system builds a new composite service, which selects all available qualified grid service for composition...
IEEE P1900.4 is an emerging standard for optimized radio resource utilization where cognitive radio technologies are used for efficient spectrum utilization. In this paper, we design and implement a cognitive wireless network system based on open documents of IEEE P1900.4, and evaluate its performance using UDP streaming and HTTP download. Our experiments show interesting results that total network...
This is an introduction to the proceedings of the MWS 2007 workshop held at EDOC 2007. It first explains the motivation for and background of the workshop. Then, it contains a short description of the keynote, each long and short peer-reviewed paper, and the discussion session "impact of various execution environments on middleware for web services". After the closing statements, MWS 2007...
